Name: Ag@SiO2Nanoparticles

Product Overview

Silica-coated silver nanoparticles (Ag@SiO2) is a nanocomposite material with special structure and properties. Ag@SiO2 nanoparticles have a typical core-shell structure, that is, silver nanoparticles serve as the core and the silica shell The layers are tightly packed around the core. This structure not only improves the stability of silver nanoparticles, but also gives them new properties. The silica shell provides good chemical stability to the silver nanoparticles, preventing them from reacting with chemicals in the environment. Maintaining its original physical and chemical properties, the thickness and morphology of the silicon layer can be precisely controlled by adjusting the parameters during the preparation process. Ag@SiO2 nanoparticles have good stability, biocompatibility, controllability, optical properties, antibacterial properties and surface functionalization, and have shown broad potential in biomedicine, optical sensing, drug delivery and other fields. Application prospects.

Product Features

Chemical stability: The silica shell provides good chemical stability to the silver nanoparticles, preventing them from reacting with chemicals in the environment, thereby maintaining their original physical and chemical properties.

Optical properties: The presence of silica shell can affect the optical properties of silver nanoparticles, such as plasmon resonance wavelength. By adjusting the thickness and morphology of the shell, precise control of the optical properties of silver nanoparticles can be achieved.

Antibacterial properties: Silver nanoparticles themselves have excellent antibacterial properties, and coating with silica shell can further improve their antibacterial effects. At the same time, mesoporous silica-coated silver nanoparticles (Ag@mSiO2) also have a larger specific surface area and better antibacterial persistence.

Biocompatibility: Ag@SiO2 nanoparticles have good biocompatibility, which means they can be used safely in living organisms without causing severe immune reactions or toxic reactions. This feature makes it have potential application value in the biomedical field, such as drug delivery, bioimaging, etc.

Application Fields

Antibacterial materials: Ag@SiO2 nanoparticles can be used to prepare various antibacterial materials, such as antibacterial coatings, antibacterial textiles, antibacterial plastics, etc. These materials have broad application prospects in medical, food packaging, household products and other fields.

Biosensing: Using the optical properties of Ag@SiO2 nanoparticles, highly sensitive biosensors can be constructed for detecting biomolecules, ions and other targets.

Catalysis field: Silver nanoparticles show excellent performance as catalysts in multiple chemical reactions, and coating with silica shell can further improve their catalytic activity and stability.
